Web of Things (WoT)


WoT is a way to realize the IoT.
•
IoT(Internet of Things): Global infrastructure enabling advanced services by
interconnecting Things
•
WoT(Web of Things): All Things connected and controlled through the Web
Physical devices can be accessed as resources of the web and
services/applications can be provided based upon a web-based service
environment.

Use Case of WoT at Home

Smart Home is one of the most representative use case of WoT.
•
User’s demands to remotely control & monitor home appliances using mobile
devices are increasing.

ITU-T Y.2063: Framework of the WoT



Released at July of 2012 by ITU-T Study Group 13
Describes the overview, identifies the requirements to support the WoT
Specifies the functional architecture for WoT
<Conceptual Model of the WoT, ITU-T Y.2063 >

WoT Functional Architecture of ITU-T Y.2063

Divided into 3 layers: service, adaption and physical layer
•
•
•
Service layer makes a service available & manage it
Adaption layer interacts with physical devices for the translation of different
protocols and message formats
Physical layer includes physical devices
5
Need for HES Application Model of WoT

The WoT model of ITU-T Y.2063 is a generic model independent of
application domains.

Needs to be rebuilt to be applied to the specific domains considering their
environmental characteristics

A model of WoT system for HES application needs to be defined.

Considers integrating the WoT with the existing HES components and protocols

Defines the functional roles of HES components and their interaction for WoT
services

The application model is essential to guarantee the interoperability
among HES devices for WoT services

Proposal of New Standard
 Title
ISO/IEC15067-x HES application model: Model of a WoT(WebofThings) System for HES
 Scope
This standard specifies a generic high-level model for a WoT system using HES that
enables a consumer to control and manage the home appliances inside the house as
well as outside the house using a method known as WoT(Web of Things).
• Develop architectural models specially considering HES
• Specify key services in HES
• Specify communication messages needed to support the services
 Purpose and Justification
The models in this standard foster interoperability among WoT products from
competing or complementary manufacturers.
